Decoding the texts everyone gets
A one-word "sure" is agreement with the enthusiasm drained out. They'll do it — but you've been told, quietly, that they'd rather not, or that something about how you asked landed wrong.
The gap between "sure!" and "sure." is the whole message. If you got the period, it's worth checking whether the ask, or the timing, rubbed them the wrong way.
Decode YOUR exact message → it depends on contextThese are the patterns — but the same word means different things from different people. Sided reads your actual conversation and tells you what THIS person means, and what to say back.
